IMPROVEMENT IN PARING-KNIVES.

Specification forming part of Letters Patent No. 203,862, dated May 21,1878 application filed October 27, 1877.

To all whom it may concern:

Beit known that I, JOHN H. WILHELM, of Denver, in the county of Arapahoeand State of Colorado, have invented a new and useful Improvement inPairing-Knives, with an improved adjustable guard attached, whichimprovement is fully set forth in the following specification andaccompanying drawing, in which- Figure 1 is a perspective view of theknife with the guard attached. Fig. 2 is a View of the knife, showingthe notch and stop) by means of which the clasps of the guard are heldin place. Fig. 3 is a section of the point of the knife on a b, as shownat Figs. 1 and 6. Fig. 4 is a section of the blade of the knife on e f,Fig. 1, showing the heel-clasp ofthe adjustable guard. Fig. 5 is asection of the knife-blade on c d, showing the point-clasp of theadjustable guard. Fig. 6 is a top view of the knife-blade, with theguard attached.

The object of my invention is to furnish a convenient knife for gradingthe paring and slicing of fruits and vegetables, for removing the eyesand specks from the same, and to protect the thumb against the sharpedge of the blade.

These objects I accomplish mainly by means of spring-clasps havingperforated flanges, the wire guard, Figs. 1, 4, and 6, andthe beveled orrounded point of the knife-blade, (shown at Fig. 3, and at a b, Figs. 1and 6,) all as hereinafter more fully described and claimed.V

In Figs. 1, 4, and 6, g represents a springclasp with a perforatedflange, made of any The clasp and lian ge are cut and crimped from thesame piece of metal. The heel-clasp, Fig. 4, shows the perforations inthe flan ge into which the wire guard 'n is slipped. The guard is heldin place by means of the shoulders h. (Shown at Fig. 6.) An easy rollingmovement is thus given to the guard n, which facilitates its operation.The clasp, Fig. 4, is held from slipping forward on the blade of theknife by means of the edge, which is turned down, aS shown at l, Fig. 1,and which catches into the notch of the knife-blade, (shown at k, Fig.2,) and is firmly held in place on the blade by the edges of thespring-clasp, which are slightly bent around on the back of the blade,Fig. 4. The point-clasp, Fi'g. 5, is constructed and held in place onthe blade in a similar manner, and prevented from slipping forward bymeans of the stop m, Figs. 1 and 2. The guard a may be adjusted by meansof the several perforations shown in the flanges of the clasps, Figs. 4and 5.

The point of the knife-blade is beveled or rounded on one side, as shownat Fig. 3, which is a section on a b, Figs. 1 and 6, to facilitate itsoperation in removing the eyes from potatoes, and for like purposes. Thepointclasp, Fig. 5, may readily be attached to the blade ofthe knife,Fig. 2, and removed therefrom by slipping it over the point of theknife. To prevent dulling the knife the heel-clasp, Fig. 4, should beslipped on the blade and removed from the saine close to the handle ofthe knife.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The stop m, in combination with the beveled or rounded point of theknife-blade, and with the pointclasp, substantially as shown anddescribed.

2. The spring-clasps g, adapted to pass over the blade, and havingperforated lianges to secure the wire guard in place, substantially asspecified.

3. The combination of the Springclasps g, the wire guard n, and theknife-blade, substantially as described and shown, and for the purposeset forth.

JOHN H. WILHELM.
